In view of the rapidly progressing urbanization worldwide, informal settlements especially in the cities of the global south must be a focus of our attention, because the majority of new city inhabitants in future will settle in these unplanned extensions of urban centers. The tools and methods of conventional urban planning have so far been unable to tackle this phenomenon. New approaches are required that combine top - down planning and bottom-up initiatives to create sustainable and viable living environments. The Moravia Manifesto presents the alternative planning approaches put forward by an international Think&Do tank, which were developed together with local participants from the Moravia informal settlement at the heart of the Colombian metropolis Medellín. This new planning approach is contextualized by essays and international case studies. Urban Coding shows new ways of how planning, politics, economy and administration can initiate and implement innovative and inclusive urban transformation processes in coproduction with local communities.
